This theoretical contribution shows a simple way in which the quantity equation can be derived as a long-term equilibrium solution for the case of a closed economy and an open economy, respectively. It is shown first for the case of a closed economy which parameters stand behind "velocity" and...

While the IS/LM-AS/AD model is still the central tool of macroeconomic teaching it has been criticised by several economists. The model is unable to deal with a monetary policy that uses the interest rate as its operating target ( Romer [2000]). Walsh [2002] has criticised that it is not suited...

We study the conduct of monetary policy in a continuum of small open economies and obtain a novel closed-form solution that does not restrict the elasticity of substitution between home and foreign goods to one. We give an exact characterization of optimal monetary policy and welfare with and...

Do financial frictions call for policy cooperation? This paper investigates the implications of financial frictions for monetary policy in the open economy. Welfare analysis shows that there are long-run gains which result from cooperation, but, dynamically, financial frictions per se do not...

Inflation volatility is clearly important for structural analysis, forecasting and policy purposes, yet it is often overlooked in the literature. This paper compares inflation volatility among advanced open economies with inflation targeting monetary policy frameworks. The results of the...

For the open economy the workhorse model in intermediate textbooks still is the Mundell-Fleming model, which basically extends the IS-LM model to open economy problems. The purpose of this paper is to present a simple New Keynesian model of the open economy, that introduces open economy...
